Results of self-assessment evaluation
| Improvement on treated side at T1 compared to T0 (vs untreated side) | Significant difference at T1 between treated and untreated | Significant difference in evolution between the treated and untreated | |
|---|---|---|---|
| Wrinkles | 13.6% (4.8%) | Yes (P=0.004) | |
| Roughness | 3.8% (−5.1%) | Yes (P=0.028) | Yes (P=0.016) |
| Fine lines | −3.1% (−10.5%) | ||
| Nasolabial fold | 21.3% (11.6%) | Yes (P=0.089) | |
| Elasticity | 11.2% (0.5%) | Yes (P=0.003) | |
| Firmness | 23.1% (2.5%) | Yes (P=0.003) | Yes (P=0.001) |
| Radiance | 26.3% (14%) | Yes (P=0.011) | Yes (P=0.026) |
| Softness | 2.1% (−7.4%) | Yes (P=0.018) | Yes (P=0.016) |
| Under-eye dark circles | 18.8% (0%) | Yes (P=0.001) |
Notes: At T0 and T1, volunteers were asked to score some parameters which characterized their skin (described as presence/absence and the intensity of each parameter). Self-assessment showed improvement on treated side for nine of the ten parameters evaluated; in all cases, nontreated side was felt as less improved or even to have worsened. Difference at T1 between treated and untreated sides were significant for seven of the ten parameters, and trend for one. Significant evolution of treated side was noticed for roughness, firmness, radiance, and softness, compared to untreated hemiface.
Abbreviation: T, time.
